A block of mass 6.7 kg starts sliding down from rest, on an inclined plane of length l=2.5 m and inclinedat angle 0=30° to a horizontal floor. The coefficient of friction between the block and the plane areHs-0.6 and H-0.25. At the bottom of the inclined plane, the block continues sliding along the horizontalfloor until it comes to stop after traveling a distance d=7.1 m. The coefficient of kinetic friction betweenthe block and the floor is H(x)=0.04X+0.1, where x is in meter. What is the work done by the friction forcewhile the block sliding along the floor?

Given: The mass is m=6.7 kg. The travelling distance is d=7.1 m. The friction between the block and…

You have devised an experiment to measure the kinetic coefficient of friction between a ramp and a mass. You place the mass on the ramp at an angle high enough that the mass starts sliding. You measure the time it takes to fall down a known distance. The time it takes to fall down the 45 degree ramp starting from a standstill is At = 0.46 sec, m=1 kg, and the distance it falls, Ax , is 0.5 m. What is µk? m Дх in At Uk
